TIRE- SET.

SPECIFICATION forming part of Letters Patent No. 722,993, dated March17, 1903. Application filed April 15, 1902. Serial No. 102,971. (Nomodel.)

To aZZ whmn it floaty concern.-

Beit known that 1, JOHN BRITON KIMBELL, a citizen of the United States,and a resident of Alpharetta, in the county of Milton and State ofGeorgia, have invented a new and Improved Tire-Set, of which thefollowing is a full, clear, and exact description.

This invention relates to an apparatus for shrinking or compressingtires when cold upon vehicle-wheels, so as to cause them to tightly fitthe same.

This specification is an exact description of one example of myinvention,while the claims define the actual scope thereof;

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a plan view of the table. Fig. 2 is a view showing the wheelplaced on the table and the shrinking-blocks in place. Fig. 3 is a viewof the hand-wrench. Fig. 4 is a view showing one of the compressor-rods.Fig. 5 is a view showing one of the shrinking-blocks. Fig. 6 is 'aperspective View of one of the blocks used with the compressorrods. Fig.7 is a view of one of the coni pressor-rods with its not in place. Fig.8 is a vertical section of the parts as shown in Fig. 2, and Fig. 9 is aview showingthe apparatus used on a wheel the diameter of which isgreater than that shown in Fig. 2.

The apparatus comprises a table which is adapted to lie horizontally andis built up of any suitable number of tapering sections 10, separatedfrom each other by radial spaces and arranged in general circular form.These sections 10 are fastened rigidly at their inner ends to a hub-likemember or disk 11, which has horizontal flanges 11, to which thesections 10 are bolted. Near their outer portions the sections 10 arerigidly connected on their under sides with a ring or annulus 12. Ateach side edge of the sections 10, adjacent to their outer ends, notches14 are formed, these notches being opposite each other in pairs andforming radial spaces respectively in line with the spaces between themajor portions of said sections.

15 indicates legs by which the table is supported in the horizontalposition explained,

and 15 indicates knees and fastening devices for engaging the legsrigidly with the table.

As shown best in Fig. 8, the wheel is placed on the table with its hub16 in the cup or hublike member 11, the spokes l7 and felly 181ying overthe top of the table formed by the sections 10. The hub 16 is heldsecurely and rigidly in place by a rod 19, which is passed through thecup or hub-like section and through the hub 16 and provided at its lowerendwith ahead and at its upper end with a nut and hand-Wheel 20- fortightening it in place. This holds the hub. 16 rigidly in a centralposition and keeps the spokes and felly of the wheel pressed down on topof the table.

Lying in the radial spaces between the sections 10 of the table are thecompressor-rods 21, which may be of any suitable number and which havehooks 22 at their inner ends, these hooks engaging with the inner edgesof the horizontal flanges 11 of the hub-like portion or cup 11 of thetable. ends the compressor-rods 21 are provided with nuts 23, and thesenuts bear on compressor-blocks 24, any suitable number of which may beemployed and which are slidably fitted on the respective rods 21 v andwhich are arranged to slide in the radial spaces formed by the opposingrecesses 14. In case of small wheels-tor example, the front wheels ofvehicles-two or more spacing compressor-blocks 25 are employed, as shownin Fig. 2, these blocks serving to transmit the pressure of thecompressing-blocks 24 to the tire of the wheel. Fig. 9, however, showsthe invention in use in connection with a relatively large wheel, inwhich only one series of spacing compressor-blocks 25 is employed. This,of course, does not concern the essential portions of my invention, butdepends merely upon the size of the wheel which is being worked.

In using the invention the wheel is placed on the table, as explained,and the spacerblocks 25 are properly disposed so that the pressure ofthe blocks 24 will be communicated to the tire of the wheel. The nuts 23are then tightened by means of any suitable devic'e--for example, bymeans of the wheelwrench 26. (Shown in Fig. 3.) This causes At theirouterthe blocks 24 to be forced up firmly to the wheel, and through themovement of the spacer-blocks 25 the tire is shrunk or compressed,andthus fitted tightly on the felly of the wheel.

Various changes in the form and details of my invention may be resortedto at will Without departing from the spirit thereof. Hence I considermyself entitled to all forms of the invention as may lie within theintent of my claims.

Having, thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A tire-set, comprising a table having acentrally-located hub-like member or dish, formed with aninwardly-projecting flange, compressor-rods, each having at one end ahook to engage said flange, means at the outer end of eachcompressor-rod to apply pressure to the tire, and a means for holdingthe hub of the Wheel in said hub-like member or dish.

2. A tire-set, comprising a table formed of tapering sections separatedfrom each other to form radial spaces, a centrally-disposed hub-likemember or dish fastened. to the inner ends of said tapering sectionsand-having an inwardly-projecting flange, means connected to the outerends to hold them rigid, compressor-rods having hooks engaged with theflange of the hub-like member or dish and extending outward through saidradial spaces, means at the outer ends of the compressor-rods forapplying pressure to the tire, and means in the hub-like member or dishfor holding the hub of the wheel therein.

3. A tire-set comprising a table having radial spaces therein and acentrally-disposed hub-like member or dish, the latter having aninwardly-projecting flange, compressorrods having hooks connected withsaid flange of the hub-like member or dish and extending outward throughsaid radial spaces, means on the outer ends of the compressor-rods forapplying pressure to the tire, and means at the hub-like member or dishfor holding the hub of the wheel therein.

4. A tire-set, comprising a table formed of a number of taperingsections separated from each other to form radial spaces, acentrallydisposed hub-like member or dish fastened to the inner ends ofthe said tapering sections, an annulus fastened to the outer portions ofthe sections to hold them rigid, said hub-like member having aninwardly-extending annular flange, compressor-rods having hooks engagedwith said flange, the compressor-rods extending outward through saidradial spaces, means at the outer ends of the said compressor-rods forapplying pressure to the tire, and means at the said hub-like members ordish for holding the hub therein.

5. A tire-set, comprising a table having a number of radial spacestherein, and a centrally-disposed dish or hub member opening at itsupper side and extending below the plane of the table, compressor-rodslying in said radial spaces of the table and having their inner endsengaged with the upper portion of the said dish, means at the outer endsof the compressor-rods for applying pressure to the tire, and means atthe said dish or hub member for holding the hub down firmly in the same.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

JOHN BRI TON KIMBELL.
